Applicant's summary and conclusion

Conclusions:
The melting point could not be determined as n-hexyl lithium is a liquid at room temperature and atmospheric pressure. The freezing point is below -62 °C.
Executive summary:

The melting point could not be determined as n-hexyl lithium is a liquid at room temperature and atmospheric pressure. The freezing point is below -62 °C.

According to column 2 of REACH Regulation (EC) No. 1272/2006 the study does not need to be conducted below a lower temperature limit of -20 °C.
